      Subcommittee on Investigations and Oversight,
               Committee on Science, Space, and Technology,
                                                   Washington, D.C.

    The Subcommittee met, pursuant to notice, at 2:01 p.m., in 
room 2318, Rayburn House Office Building, Hon. Jay Obernolte 
[Chairman of the Subcommittee] presiding.

[GRAPHIC(S) NOT AVAILABLE IN TIFF FORMAT]

    Chairman Obernolte. The Subcommittee on Investigations and 
Oversight for the Committee on Science, Space, and Technology 
will come to order.
    Without objection, the Chair is authorized to declare a 
recess of the hearing at any time.
    I'd like to welcome everyone to today's hearing entitled 
``Environmentalism Off the Rails: How CARB Could Cripple the 
National Rail Network.'' I'd like to begin by recognizing 
myself for 5 minutes for an opening statement.
    I want to thank every one for being here and to our Ranking 
Member for being here for what's, for me, a very important 
hearing. The purpose of our hearing today is to discuss a 
proposal by the California Air Resources Board that could 
cripple the national freight network. The Air Resources Board, 
which we call affectionately CARB for short, is seeking a 
waiver from the EPA (Environmental Protection Agency) that 
would require all locomotives manufactured after 2035 that 
travel through the State of California to operate in a zero-
emissions configuration.
    Now, the idea of zero-emissions locomotives sounds very 
supportable. It certainly does to me. Unfortunately, though, 
the technology to actually accomplish this does not currently 
exist. In fact, there are actually many who doubt it could ever 
be achieved. Even if this technology became feasible, we are 
decades away from making zero-emission locomotives a reality in 
the freight rail industry.
    Currently, the vast majority of freight rail moves by 
diesel electric trains, which convert mechanical energy from 
diesel engines into electrical power that moves the wheels and 
propels the train down the track. Because diesel is 27 times 
more energy-dense than a lithium battery, a typical diesel 
electric train can convert 5,000 gallons of diesel into 100 
megawatt hours of energy.
    Meanwhile, the largest, most powerful train battery 
technology commercially available today holds only between 5 
and 8 megawatt hours of energy. That means that CARB is 
expecting the rail industry to invent a battery that can hold 
up to 20 times more energy capacity than currently exists and 
then mass produce that technology and include it on every train 
in the Nation within the next 6 years.
    Now, to be clear, I am certainly not saying that industry 
shouldn't strive to make our freight network cleaner. And I 
consider myself an environmentalist, and I think most of us on 
the dais would make that same statement. But to impose an 
arbitrary deadline that is not supported by science shows that 
CARB has abandoned its mission to protect Californians from 
harmful air pollution, to instead support unrealistic, 
idealistic policies. Worst of all, to me, CARB's zealous 
actions are threatening to derail years of progress made by 
railroads to reduce emissions.
    Through decades of investments and billions of dollars in 
research, the rail industry can now move 2,000 pounds of 
freight 450 miles on a single gallon of diesel fuel. The rail 
industry continues to make investments to reduce emissions and 
other particle contaminants through technologies such as 
positive train control and trip optimization. As a result, 
trains today account for less than one-half percent of U.S. 
greenhouse gas (GHG) emissions. Even considering only the 
transportation sector and only transportation-related 
emissions, rail accounts for less than 2 percent.
    Unfortunately, imposing this harsh and unrealistic 
regulation will likely have an effect counter to the goal of 
this regulation and of CARB's mission. If the EPA allows CARB 
to implement this proposal and the rail industry is unable to 
meet the impossible demands, we will likely see a shift in 
modal transportation where all freight is no longer moved by 
rail but is instead transported via trucks within the State of 
California.
    Unfortunately, heavy-duty trucks, which currently account 
for 23 percent of emissions, would then become the primary 
means of freight transport in California. Transporting freight 
by truck emits roughly three times as much greenhouse gases as 
transporting it by rail. This shift would undeniably result in 
a massive increase in greenhouse gas emissions, which is the 
exact opposite of what CARB claims this regulation is meant to 
accomplish.
    CARB also wants to ban the use of any locomotive that's 23 
years of age or older. Buying a locomotive is not like buying a 
car. The average class 1 freight locomotive has a service life 
of 40 to 50 years. Locomotives are multimillion-dollar 
investments that only make sense if used for extended periods 
of time, similar to an aircraft or a large container ship. For 
many short line railroads in my State, buying new locomotives 
is simply not an option, and forcing them to do so means they 
will have to simply cease operations. California knows this and 
even admits it. In the proposed regulation CARB states that 
some smaller class 3 locomotive operators will face significant 
compliance costs and projects that it will likely--likely--lead 
to their elimination if they are unable to offset them.
    And unfortunately, the negative downstream effects of this 
regulation won't be confined to my State of California. The 
supply chain implications for this proposal could be far 
larger. We all remember the supply chain nightmares that our 
country experienced several years ago when there were 70 
container ships were anchored off the coast of California 
waiting for space to open in the ports of Los Angeles and Long 
Beach. This event caused a supply chain disruption that was 
felt nationwide. But if this waiver is granted, the new CARB 
rule could create another similar situation with millions of 
tons of goods waiting to be moved from ships onto trucks 
instead of trains because CARB decided to ignore science and 
plain common sense. Except, unlike the previous disruption, 
this one would be permanent.
    The House Science, Space, and Technology Committee is 
meeting today to talk about science and technology. We're here 
to analyze where the science and technology of rail is 
currently at and what steps can be taken to reduce emissions 
and other particle pollutants in a smart and responsible way. 
So I want to thank you all for your willingness to be here to 
discuss this critically important topic.
    [The prepared statement of Chairman Obernolte follows:]

    Chairman Obernolte. I'd now like to recognize Ranking 
Member Foushee for her opening statement.
    Mrs. Foushee. Thank you, Chairman Obernolte, and thank you 
to our witnesses for appearing before the Subcommittee today.
    Since joining the Science Committee, it has been my 
privilege to participate in hearings that have showcased the 
very best of the Committee's mandate to lead the way in 
advancing the breakthroughs and innovations of the future. This 
Committee works best when we set aside narrow and parochial 
thinking in favor of a broad and forward-looking perspective 
that allows us to dig deep into solutions to pressing 
scientific challenges.
    With that in mind, I feel compelled to note that the 
subject of today's hearing has virtually no connection to the 
Science Committee's jurisdiction. We're here to discuss an 
environmental regulation at the State level that is directed at 
freight rail operations, none of which falls under the 
Committee's purview. It is my hope that after today's hearing 
concludes, we will refocus on the challenges and opportunities 
facing the Federal research enterprise. Still, I will always 
accept the opportunity to discuss the path forward for a low-
carbon future and the health risks faced by environmental 
justice communities.
    Diesel-powered freight rail operations are a significant 
source of air pollution, a notable contributor to climate 
change, and a major environmental hazard for frontline 
communities located around major railyards. The State of 
California, as a part of its obligation to provide clean air to 
its residents, aims to reduce these harms with the end-use 
locomotive regulation.
    The rule requires the freight rail sector to adopt cleaner 
locomotive technologies in the coming decades, and it seeks to 
advance a transition to zero-emission rail operations that 
would emit that would mirror America's broader shift to a clean 
energy future. Fortunately, the State's action rests on a solid 
foundation in terms of public health, cost-benefit analysis, 
and technical feasibility.
    The end-use locomotive regulation would have sweeping 
public health benefits. According to CARB's modeling and 
analysis, the rule would reduce statewide locomotive emissions 
by approximately 7,400 tons of particulate matter and 386,000 
tons of nitrogen oxide between 2023 and 2050. It would reduce 
greenhouse gas emissions from locomotives by 21.6 million 
metric tons. It would reduce hospital admissions and emergency 
room visits and lead to 3,200 fewer premature deaths. It would 
even reduce the cancer risk for communities located around 
major railyards by over 90 percent by 2045. These statistics 
translate to real cancer rate droppings, real lives saved, and 
air that will be cleaner and healthier for millions of 
Americans.
    And despite the predictable complaints from industry, there 
is every reason to believe that decarbonizing the rail sector 
is realistic and achievable. We don't have to take CARB's word 
for it. An independent peer-reviewed 2021 study led by 
researchers at Lawrence Berkeley National Laboratory made a 
similar finding, concluding that, in the near future, battery 
electric trains can achieve parity with diesel electric trains 
nationally in terms of costs. Based on their analysis, these 
independent researchers further concluded that re-
retrofitting--I'm sorry, retrofitting diesel electric 
locomotives with battery electric technology could save the 
U.S. freight rail sector billions of dollars, while yielding 
environmental, health, and grid resilience benefits. Thus, the 
argument that zero-emission alternatives will not be available 
and that their adoption would be prohibitively expensive does 
not appear to reflect the best available science.
    I hope today's discussion keeps in mind that real lives are 
at stake in the transition to cleaner freight rail operations. 
Frontline communities should not be forced to sacrifice their 
health and their lives because others are reluctant to invest 
in the technological solutions made available by a clean energy 
future.
    And, Mr. Chair, I would yield back.

that in the near future, ``battery-electric trains can achieve 
parity with diesel electric trains'' nationally in terms of 
cost. Based upon their analysis, these independent researchers 
further concluded that ``retrofitting diesel-electric 
locomotives with battery-electric technology could save the US 
freight rail sector billions of dollars while yielding 
environmental, health, and grid-resilience benefits.'' Thus, 
the argument that zero-emission alternatives will not be 
available, and that their adoption would be prohibitively 
expensive, does not appear to reflect the best available 
science.
    I hope today's discussion keeps in mind that real lives are 
at stake in the transition to cleaner freight rail operations. 
Frontline communities should not be forced to sacrifice their 
health--and their lives--because others are reluctant to invest 
in the technological solutions made available by a clean energy 
future. Mr. Chairman, I yield back.

    Chairman Obernolte. Thank you very much, Ranking Member 
Foushee.
    I'll now recognize the Ranking Member of the Full 
Committee, Ranking Member Lofgren, for 5 minutes for her 
opening statement.
    Ms. Lofgren. Well, thank you Chairman Obernolte, for this 
opportunity to discuss how our shared home State of California 
is working to protect the health of our constituents. While 
this is not a typical Science Committee hearing, I'm glad it 
offers me a chance to welcome Alan Abbs from the Bay Area 
Quality Air Management District. He and his colleagues work 
hard to address harmful air pollution, including eradicating 
the use of leaded aviation fuel in my district and beyond.
    California has unique challenges that worsen our air 
quality. We have major ports, increasingly intense wildfires, 
and stunning California geography, which leads to an 
accumulation of pollution in mountain valleys. These obstacles 
are why the Clean Air Act allows California to seek waivers to 
go above and beyond Federal standards to improve the State's 
air quality.
    In November, EPA issued a policy change that explicitly 
allows California to seek an EPA waiver to issue locomotive-
specific regulations. As EPA explained in its notice, this 
policy change aligns with the legislative intent of the Clean 
Air Act. I was glad to see this because if California can't 
regulate locomotives, it leaves a huge gap in the protection to 
frontline communities.
    According to CARB's analysis, the regulation we're here to 
discuss today will reduce cancer risk around railyards by an 
estimated 90 percent. It will result in 1,500 fewer emergency 
room visits and 3,200 fewer premature deaths. Beyond those 
health benefits, this policy makes sense in cost-benefit terms. 
CARB estimates that the monetized health benefits outweigh the 
equipment and labor costs by over $18 billion. That's a 
reflection of just how much the public would benefit from the 
shift to zero-emission rail alternatives and freight 
operations.
    Now, any regulation that changes the status quo is going to 
demand some upfront costs, and it's not surprising to see 
resistance from the railroad industry. Fortunately, there's 
good news for them on the affordability issue coming from just 
outside my backyard. As the Ranking Member has mentioned, 
researchers at Lawrence Berkeley National Lab led a recent 
analysis that concluded the switch from diesel to battery 
electric locomotives could save U.S. freight rail sector not 
just a lot of money, $94 billion over 20 years in sector-wide 
net present value. And this technology is not pie-in-the-sky. 
Commercial availability is projected within the next 10 years. 
CARB took that timeline into consideration when choosing to 
phase in the requirements with milestone options available 
through 2047. I'd also note that California is moving the 
trucking industry also into zero emissions.
    Now, the science behind the public health benefits is 
clear. This regulation will save lives, and I hope EPA follows 
the science in its consideration of granting the waiver.
    This is also a topic with a lot of exciting technology. To 
highlight, the regulation is going to spur adoption of state-
of-the-art zero-emission locomotives as well as tier 4 
technologies that have been available for a decade. All of 
these modern alternatives are a drastic improvement over diesel 
engines, some of which have been chugging through our 
community, emitting harmful exhaust for half a century.
    So I thank the Chairman for this hearing. I thank the 
witnesses for their participation. I look forward to their 
testimony, and I yield back.
    [The prepared statement of Ms. Lofgren follows:]

    Good afternoon, and thank you to Chairman Obernolte for 
this opportunity to discuss how our shared home state of 
California is working to protect the health of our 
constituents. While this is not a typical Science Committee 
hearing, I'm glad it offers a chance for me to welcome Alan 
Abbs, from the Bay Area Air Quality Management District (AQMD). 
Mr. Abbs and his colleagues work hard to address the harmful

    Any regulation that requires a change to the status quo is 
going to demand some up-front costs, so it's not surprising to 
see resistance from the railroad industry. Fortunately, there's 
good news for them on the affordability issue, coming from just 
outside my backyard. Researchers at Lawrence Berkeley National 
Laboratory led a recent analysis that concluded the switch from 
diesel to battery-electric locomotives could save the U.S. 
freight rail sector $94 billion over 20 years in sector-wide

commercial availability is projected within the next ten years. 
CARB took that timeline into consideration when choosing to 
phase in the requirements, with milestone options available 
through 2047.
    I want to be clear--I think the Science Committee is an 
awkward venue for this particular discussion. I don't think my 
role as Ranking Member is particularly relevant to my support 
for state-level California regulatory actions. But regardless, 
some Science Committee tenets certainly hold true. The science 
behind the public health benefits is clear. This regulation 
will save lives, and I hope EPA follows the science in its 
consideration of granting the waiver. This is also a topic with 
a lot of exciting technology to highlight--this regulation will 
spur the adoption of state-of-the-art zero-emission locomotives 
as well as Tier 4 technologies that have been available for a

improvement over diesel engines, some of which have been 
chugging through our community, emitting harmful exhaust, for 
half a century.
    Thank you to our witnesses for joining us today. I yield 
back.

    Chairman Obernolte. Thank you very much, Ranking Member 
Lofgren.
    So, obviously, we have a difference of opinion on this 
topic, and that's why we have our expert witnesses here to help 
us navigate that. And we're going do that in a respectful and 
inclusive way.
    I did, however, want to briefly address the issue of 
jurisdiction before we get into the testimony since our 
witnesses aren't equipped to answer that question, and it's 
something that I take very seriously. I'd like to remind my 
colleagues that this Committee has jurisdiction over 
environmental research, development, and commercial application 
of energy technology. We also have jurisdiction over the 
scientific issues related to environmental policy. And we're 
here today discussing whether it's feasible to deploy 
alternative energy technologies nationwide, so that is 
absolutely within the jurisdiction of this Subcommittee.
    And I'd also like to highlight that many of the 
technological advances we're going to be discussing today came 
about as a result of the Consolidated Rail Infrastructure and 
Safety Improvement grants that are directly within the 
jurisdiction of this Committee, so, you know, very apropos to 
what we're going to be discussing.
    And then lastly, it was--has been raised that this might be 
a State issue and so might not be appropriate to have a hearing 
at the Federal level. I think that that is untrue for two 
reasons. First of all, the fact that what we're discussing is a 
request by CARB of the EPA to grant a waiver, which is a 
Federal issue. But the second larger issue is that we are 
talking about a topic--the topic of the regulation of Federal--
of railways and of emissions of locomotives that is already 
federally preempted. And we're going to be discussing the 
dangers of allowing 50 different State regulations to exist 
concerning the emissions of diesel locomotives and the 
impossibility of having a national freight network when every 
time you crossed a Stateline, you had to change locomotives.
    So I take those jurisdictional issues that were raised by 
my colleagues very seriously. That is why I felt that this 
hearing was very appropriate.
    So I want to move into our witness testimony. Our first 
witness is Mr. Ian Jefferies, who is President and Chief 
Executive Officer of the Associated--Association of American 
Railroads (AAR). Mr. Jefferies, you are recognized for 5 
minutes.

                TESTIMONY OF MR. IAN JEFFERIES,

             PRESIDENT AND CHIEF EXECUTIVE OFFICER,

               ASSOCIATION OF AMERICAN RAILROADS

    Mr. Jefferies. Good afternoon. Chairman Obernolte, Ranking 
Member Foushee, and Members of the Subcommittee, thank you for 
the opportunity to be here today where I have the privilege of 
representing the Nation's freight railroads. And through $21 
billion in annual private investments and a 140,000-mile 
interstate network, rail touches most of the economy and 
facilitates our modern way of life.
    Railroads provide the greenest form of land transportation, 
moving 40 percent of long-haul freight, yet accounting for only 
2 percent of transportation emissions and less than 1 percent 
of total emissions. Further reducing our environmental 
footprint is a core business goal, and, as such, I relish the 
opportunity today to discuss CARB's end-use locomotive 
regulation, which seeks to begin phasing out diesel locomotives 
by 2030. Now, doing so requires the EPA to grant a waiver 
request, which is now under review.
    CARB's regulation is unrealistic, and frankly diverges from 
this Administration's Department of Energy's (DOE's) recent 
budget requests, which includes funds to support a 50 percent 
reduction in GHG emissions in a locomotive engine by the year 
2030.
    I must state the obvious clearly. EPA must reject CARB's 
request immediately and consider the following three points. 
First, the measure clearly violates both the Clean Air Act and 
interstate commerce laws set by Congress. The former prohibits 
States from regulating new or remanufactured locomotives, 
recognizing that railroading is a national process operating 
across all States. Congress reserved this job solely for the 
Federal Government.
    Second, the CARB regulation is impractical, mandating non-
viable technologies on an unrealistic timeline while grossly 
underestimating the cost of the regulation, not merely for 
railroads, but businesses that rely on rail as well.
    Last, the EPA waiver approval would create a de facto 
national regulation that would slow interstate rail traffic and 
worsen inflation. Nearly 70 percent of the national locomotive 
fleet operates in California at some point. And some other 
States would be allowed to copy the regulation if approved, and 
we cannot have a patchwork of laws across the State governing 
what is the essential interstate form of commerce.
    With that said, allow me to briefly address the landscape 
for further emissions reductions and the pitfalls of CARB's 
rule. Consider first that railroads today can move a ton of 
freight nearly 500 miles on a single gallon of diesel. And this 
is about three to four times more efficient than over-the-
highway freight. Building on their strong records, rail 
carriers are actively piloting and testing new technologies for 
their locomotive configurations. However, as locomotive OEMs 
(original equipment manufacturers) have made clear, they are 
not close to widespread commercial availability. Current 
battery hybrid locomotive technology, for example, generates a 
fraction of the power needed to replace diesel. The picture 
grows even muddier when considering the challenges of building 
out the necessary charging network.
    Manufacturers are also making progress in developing ZE 
electric switcher locomotives used in ports and yards to sort 
traffic. This technology is in its infancy, and orders for beta 
models have been significantly delayed. Yet CARB expects these 
to be the exclusive locomotives operating in yards in less than 
6 years.
    Even further CARB's rule would require railroads to deposit 
millions annually into an escrow account beginning in 2026. For 
the two class 1 railroads that operate in the State of 
California, that equates to about $800 million per year per 
railroad, and for smaller carriers, around $5 million per year. 
Economics 101 says rail transportation costs will be affected. 
Inflationary pressure would shift freight to the highways, 
increasing emissions, increasing congestion, and furthering 
damage to publicly owned infrastructure.
    A review of the public record shows that the threats are 
real and understood for many key U.S. sectors and workers. From 
farmers to chemical shippers to retailers to organized labor, 
the record overwhelmingly opposes this rule. And the U.S. 
Surface Transportation Board, which has primary jurisdiction 
over the National Rail Network, has even voiced concerns that 
CARB rule circumvents existing Federal law.
    We are encouraged to see the leadership of Chair Obernolte 
and so many congressional colleagues and writing to the EPA on 
a bipartisan basis to express concern. This input should be 
instructive to the EPA.
    Thank you, and I look forward to your--our discussion 
today.

    Chairman Obernolte. Thank you, Mr. Jefferies.
    Our second witness is Mr. Chuck Baker, President of the 
American Short Line and Regional Railroad Association.
    Mr. Baker, you're recognized for 5 minutes.

                 TESTIMONY OF MR. CHUCK BAKER,

                 PRESIDENT, AMERICAN SHORT LINE

               AND REGIONAL RAILROAD ASSOCIATION

    Mr. Baker. Thank you. Good afternoon. I am Chuck Baker, 
President of the American Short Line and Regional Railroad 
Association, representing the Nation's 600 small class 2 and 3 
short line freight railroads.
    Short lines are the first and last miles of the freight 
rail network. We move industrial, agricultural, and energy 
products from ports, factories, and farms to and from the 
larger class 1 railroads, where they bring the goods to and 
from national and global markets. Short lines used to be the 
unprofitable branch lines of the larger railroads. Luckily, 
following partial deregulation, rather than abandon those lines 
and rip up the track, the class 1 sold those lines to local 
entrepreneurs.
    Those newly minted short lines didn't have much traffic at 
the time and weren't in great shape, but the small-town local 
folks who took over those lines were eager to make a go of it. 
They ran as efficiently as possible, focused all their energy 
on getting just one more new customer or one more carload, and 
bent over backward to serve their customers, and it worked. 
Today, short lines are critical in your communities and pivotal 
in making sure that the goods that your constituents rely upon 
can get to their homes and businesses safely and affordably.
    We manage 1/3 of the freight rail network and touch 1/5 of 
all carloads, but still only account for about 6 percent of the 
industry's total revenue, and we do it all with a light 
environmental touch. Rail in total produces only 1.8 percent of 
the transportation system's greenhouse gas emissions, and about 
0.6 percent of the Nation's total emissions, and short lines 
are a minuscule fraction of that.
    The subject of today's hearing, the recent rulemaking by 
CARB, is a policy overreach of epic proportions that takes 
direct aim at our critical industry. CARB does get one thing 
right when it predicts the demise of our industry due to the 
costs of its measure, acknowledging in its own rule text that 
if these businesses--and I'm quoting. ``If these businesses are 
unable to pass on the cost of the proposed regulation to 
customers, it is possible that some of these businesses would 
be eliminated.'' Well, on behalf of these businesses, and the 
families and communities that rely on them, I am here to sound 
the alarm. They cannot pass on these costs to others, and when 
these businesses go bankrupt, the effect will ripple across our 
supply chain.
    Short lines move roughly 260,000 carloads of freight in 
California alone each year, and each carload carries the 
equivalent of three to four trucks' worth of goods. If short 
lines are driven out of business due to CARB's infeasible rule, 
that freight will move on to trucks, and businesses who have 
lost shipping options will move out of California or just 
vanish. It's a torturous trifecta of negative impacts for rail 
shippers that rely on a seamless rail network, for the economy 
as a competitive advantage for American businesses is degraded, 
and for Americans' quality of life as millions of additional 
trucks are forced onto the road, increasing congestion, 
crashes, deaths, taxes for road maintenance, and ironically, 
greenhouse gas emissions and particulate matter from shredded 
truck tires.
    In addition to the dire real-world economic and 
environmental consequences, we object for two other critical 
reasons. One, this rule is preempted by Federal law. No State 
should be able to regulate the national rail network, which is 
what this rule does. Two centuries of legal interpretations of 
the Commerce Clause and Federal statute, including ICTA 
(Interstate Commerce Commission Termination Act), the Clean Air 
Act, and the Locomotive Inspection Act, all render CARB's rule 
illegal.
    And two, its arbitrary and capricious. The rule calls on 
the rail industry to upend its financial underpinnings to adopt 
technology that is in its infancy and not ready for primetime. 
Zero-emission freight locomotives don't exist in a commercially 
viable form, they aren't at scale, and they don't have the 
power to do the job needed in harsh railroad operating 
environments. And even if all of that were magically resolved, 
they are not remotely affordable for short line railroads.
    CARB and short lines do agree that we both want to 
aggressively move to reduce our already low environmental 
impact. Our members are engaged in demonstration projects that 
move our industry closer to a zero-emission reality, including 
upgrading to cleaner locomotives, trying out alternative fuels, 
and experimenting with fuel injectors and adjunct additives to 
lower emissions quickly and affordably.
    In conclusion, Congress can provide leadership going 
forward in four ways. One, call on the EPA to deny CARB's 
request, preserving EPA as the regulator of locomotive 
emissions.
    Two, continue to fund the CRISI (Consolidated Rail 
Infrastructure and Safety Improvements) program. Short lines 
have embraced this tool to move more freight to rail and to 
upgrade to cleaner locomotives.
    Three, ensure freight rail remains a key strength of the 
Nation, supporting reasonable regulations focused on proven 
benefits and avoiding excessive subsidization of trucking.
    And four, support the basic R&D (research and development) 
activities at the DOE and DOT (Department of Transportation) 
necessary to advance the economywide transition to battery, 
electric, hydrogen, renewable diesel, and other cleaner power 
over time in a realistic and affordable fashion.
    Thank you.

    Chairman Obernolte. Thank you, Mr. Baker.
    Our third witness is Mr. Alan Abbs, Legislative Officer of 
the Bay Area Air Quality Management District.
    Mr. Abbs, you're recognized for 5 minutes.

        TESTIMONY OF MR. ALAN ABBS, LEGISLATIVE OFFICER,

            BAY AREA AIR QUALITY MANAGEMENT DISTRICT

    Mr. Abbs. Chair Obernolte, Ranking Member Foushee, and 
Members of the Subcommittee, thank you for inviting me here 
today to testify on regulations relating to the public health 
impacts of locomotive air pollution.
    My name is Alan Abbs. I'm the Legislative Officer for the 
Bay Area Air Quality Management District, which was created by 
the California legislature in 1955 as the first regional air 
pollution control agency in the Nation. The agency is 
independent from State Government and is overseen by a board of 
24 locally elected officials throughout the Bay Area. Our role 
includes regulation of stationary sources of air pollution in 
the nine Bay Area counties from Santa Clara and San Mateo 
County in the south to Napa and Sonoma in the north.
    The Clean Air Act defines roles for different levels of 
government to achieve cleaner air and improve public health 
through a framework of cooperative federalism. In drafting the 
Clean Air Act, Congress recognized California's leadership and 
long history of regulating air pollution from mobile sources, a 
role that predates the Federal statute. Because of this, the 
Clean Air Act protects California's ongoing right to regulate 
those emissions, and if California standards are at least as 
protective of public health and welfare, Federal preemption can 
be waived.
    Locomotives are one of the largest sources of health-
harming pollutants in California, and the pollution caused by 
locomotives makes it impossible for California to meet its 
Clean Air Act obligations. For highly polluted air basins such 
as the South Coast and San Joaquin, locomotives represent 31 
percent of the reductions needed to meet Federal air quality 
standards under the Clean Air Act.
    California's class 1 railroads are the Nation's largest in 
both miles traveled and operating revenues, yet they continue 
to use and are increasing use of some of the oldest and most 
polluting engines in California. EPA-compliant locomotives have 
been available since 2015, but most locomotives operating in 
California have old emissions control technology that produces 
90 percent more pollution than the current EPA standard. And 
according to CARB, in the past several years, the average 
emissions of their locomotive fleets operating in California 
have been getting worse, not better.
    In the San Francisco Bay Area, the regional air pollution 
inventory has shown that locomotives operations, including road 
hauling, switching, and rail passenger transportation 
contribute approximately 40 tons of toxic air contaminants and 
2,200 tons of ozone-causing nitrogen oxides in 2023. In recent 
years under California Assembly Bill 617, the district has been 
working with stakeholders to reduce disparities in air 
pollution exposures.
    Technical assessments indicate that locomotives are a key 
driver of cancer risk, with locomotive emissions being of 
special concern in neighborhoods adjacent to local railyards. 
For example, West Oakland is a shorefront community adjacent to 
the Port of Oakland with related railyards and four active 
marine terminals. Locomotives operating at these railyards 
account for an incremental cancer risk of about 125 additional 
cancer cases per million, exceeding EPA thresholds for 
acceptable risk. In Richmond/San Pablo it's about 100 
additional cancer risk.
    Even in areas that currently attain Clean Air Act 
standards, pollution from locomotives is a serious public 
health concern. Ninety percent of California's railyards are 
within 1 mile of vulnerable residential communities already 
highly impacted by traffic pollution, which contains the same 
contaminants as from locomotives. Until the railroads take 
serious steps to reduce emissions, these communities will 
continue to have disproportionately high levels of air 
pollution and suffer the health consequences.
    In 2023, CARB adopted a locomotive regulation and, as 
noted, would result in $32 billion in health savings, prevent 
3,200 premature deaths, and 1,500 emergency room visits and 
hospitalizations. It would also decrease the cancer risk from 
exposure by up to 90 percent in places. CARB's regulation does 
not set emission standards on new locomotives. It doesn't 
mandate the use of zero-emission technologies by 2030 or 2035. 
Instead, it calls for a steady reduction of emissions over the 
next 30 years, allowing for existing technologies to be used 
while new and more advanced zero-emission technologies are 
developed. Rail providers could make significant strides in 
meeting these regulatory requirements by just upgrading 
existing equipment to the 2015 standards. While the regulation 
does not require the purchase of new emission locomotives, it's 
worth noting that such locomotives are available for purchase 
today.
    Real quickly on incentives, since 2016, the Bay Area Air 
Quality Management District has provided incentives to upgrade 
10 switcher locomotives to current technology, as well as the 
Caltrain Electrification Project. While these projects have 
demonstrated the feasibility, it shows that incentives alone 
cannot meet this hurdle that we have of getting cleaner 
locomotives.
    So, in conclusion, thank you again for the opportunity to 
testify. I would just point out that zero-emission rail 
transportation is nothing new. Electrified rail is more than 
100 years old and is widely used around the world. Nearly every 
locomotive operating today runs on fully electric motors which 
could be powered other than using diesel generators, and diesel 
locomotives emit a toxic air contaminant for which there is no 
known safe level of exposure.
    Thank you.

    Our fourth and final witness is Dr. Tyler Dick, Professor 
at the University of Texas Austin and Lecturer and Principal 
Research Engineer with the Texas Railway Analysis and 
Innovation Node.
    Dr. Dick, you are recognized for 5 minutes.

            TESTIMONY OF DR. TYLER DICK, PROFESSOR,

       TEXAS RAILWAY ANALYSIS & INNOVATION NODE (TRAIN),

                   UNIVERSITY OF TEXAS AUSTIN

    Dr. Dick. Chairman Obernolte, Ranking Member Foushee, and 
Members of the Subcommittee, thank you very much for inviting 
me to participate in this important discussion today. My name 
is Tyler Dick, and I'm an Assistant Professor in the Department 
of Civil, Architectural, and Environmental Engineering at the 
University of Texas at Austin, where I lead the Texas Railway 
Analysis and Innovation Node, or TRAIN Lab for short.
    For the past 12 years, I conducted research on railway 
operations and energy efficiency, including the benefits and 
costs of alternative energy locomotives. The opinions expressed 
are my own and do not necessarily represent those of the 
University of Texas.
    Railways play an essential role in the U.S. economy as they 
uniquely combine the speed, energy, and efficiency to safely 
move large quantities of freight at low cost. Although U.S. 
freight railroads continue to improve fuel efficiency, they 
consume over 3 billion gallons of diesel fuel each year. 
Despite representing less than 2 percent of transportation-
related emissions, freight railroads, like all of us, must act 
to reduce carbon emissions in an effort to stem climate change 
and the health impacts on adjacent communities.
    However, freight railroads must be allowed to decarbonize 
at a pace that respects the current state of zero-emissions 
locomotive technology and in a safe manner consistent with the 
operational realities of an integrated North American rail 
network. Unfortunately, the aggressive timeline and scope 
mandated by the CARB end-use locomotive regulation cause 
concern on both of these fronts. Although a number of 
technologies offer the promise of future zero-emissions-free 
transportation, none of them are currently commercialized for 
North American heavy haul freight mainline operations. Each 
zero-emissions technology has unique technical, safety, and 
implementation challenges that must be addressed before 
widespread deployment is possible.
    Traditional electrification through overhead wire will make 
the most efficient use of electricity but requires development 
of new electric locomotive designs to meet the performance 
requirements of North American freight operations.
    Battery electric locomotives have seen limited mainline 
testing, and thus, their long-term range performance under 
various climate, topography, and operating conditions is 
uncertain, along with the viability of high-powered charging to 
support economical battery locomotive utilization.
    Hydrogen fuel cell locomotives, which make the least 
efficient use of electricity, are only beginning mainline 
prototype development, and thus, our understanding of their 
long-term performance, durability, and safety is in its 
infancy.
    While I am confident that the railroads, railway supply 
industry, government agencies, academia, and national labs can 
partner to overcome these challenges, it will require years of 
further research, development, and full-scale testing of each 
technology, followed by years of commercialization and 
deployment.
    There are numerous historical examples of railway 
technologies that appeared to be good ideas on paper or in the 
lab but failed when rushed to market without proper testing to 
expose them to the long-term realities of North American heavy 
haul freight mainline operations. With its aggressive 
timelines, the CARB regulation exposes emerging zero-emissions 
technologies to suffering the same fate.
    All three zero-emissions options will require expensive 
investments in energy supply infrastructure, whether that be 
overhead catenary wire, high-power battery chargers, or 
hydrogen production and fueling stations. Should a 
technological pathway prove not to be viable, early investments 
in associated energy supply infrastructure will become stranded 
assets. While dual-mode locomotives can help mitigate this risk 
and reduce infrastructure requirements, they remain an unproven 
concept in the freight environment and require time for 
development and testing.
    Finally, from an operational and implementation 
perspective, the CARB regulation leaves freight railroads with 
two undesirable alternatives. The first is to isolate new 
locomotives to operations within California by having all 
freight trains stop and swap locomotives at exchange points 
just outside the State. In 2016, I led a CARB-sponsored study 
that documented the negative impacts of these exchange points 
on railway operations, including a potential shift of freight 
from rail to less-efficient trucks.
    The second alternative is a network-level implementation of 
a given technology, which is impractical under the mandated 
timeline and represents a tremendous investment risk given the 
current state of zero-emissions locomotive technology. The 
combination of dual-mode locomotives and partial or 
discontinuous electrification on certain routes, in conjunction 
with batteries or hydrogen on other corridors could provide a 
third implementation pathway, but further research and testing 
is required to prove the viability of these more flexible 
concepts, and they're better fit to railway operating patterns 
across main lines of different traffic density. Unfortunately, 
the CARB regulation does not afford railroads the time or 
flexibility required to achieve this more likely multi-
technology scenario in a given timeline.
    Thank you for the opportunity to participate today. I'd be 
pleased to answer any questions.

    Chairman Obernolte. Well, thank you very much to all of our 
witnesses. That includes our witness--concludes our witness 
testimony. We'll move now to the question-and-answers portion 
of our hearing, and I will begin by recognizing myself for 5 
minutes for questions.
    Mr. Jefferies, let me start with a project that is 
critically important to my district, and it's one I think 
you're aware. BNSF has proposed to build a multimodal transfer 
facility in the city of Barstow, which is in my district. It's 
going to bring over 20,000 jobs to my community. And the 
purpose of the facility is to transfer freight from the ports 
of Long Beach to Los Angeles. Instead of putting them on 
trucks, which is what happens now, they want to put them on 
railcars, put them by rail out to Barstow, and then switch them 
to other trains going other places in the country. So that 
would shift the transportation of millions of tons of freight 
from truck to rail.
    Now, BNSF has said very publicly that should the--this 
proposed end-use locomotive rule become enforced, that they 
would no longer be able to build this facility in Barstow. And 
they're in the middle of building it now. They would stop and 
build it somewhere else because they can't afford to have 
freight locomotives that can't go into California and have to 
switch at the State border. It would make the whole system 
completely nonsensical for them, and I understand that.
    But help me understand this. It seems to me from a layman's 
perspective that for CARB to take an action that forces the 
transport of millions of tons of freight by truck that emits 
three times as much greenhouse gases per pound of freight moved 
instead of rail would be completely nonsensical and the 
opposite of the goal that they're trying to achieve. Am I 
missing something there?
    Mr. Jefferies. You're not missing anything, and it's 
completely counterintuitive to CARB's overarching goals. And 
these are the types of projects that we should all be 
celebrating and championing. This is a $1.5 billion project. It 
would be the largest intermodal yard in the country, all done 
with private dollars, not public dollars, and to your point, 
taking thousands of trucks off a very congested corridor, 
putting it on rail, getting it out of the L.A. basin into an 
area to sort for long haul across the country. It's exactly the 
sort of thing we should want to see happening, and it would be 
such a missed opportunity if this project were put at risk 
because of this rule.
    Chairman Obernolte. And to amplify the point, that corridor 
that you're referring to that is currently heavily trucked, 
that's also in my district, and so I have a vested interest in 
making sure that we shift those emissions to something that's 
three times more efficient.
    All right, Mr. Abbs, I had a question for you. I was 
interested in your testimony about the fact that freight 
locomotives in California were one of the largest emitters of 
health-threatening pollutants. And that was your oral 
testimony. In your written testimony, you had a fact that you 
quoted that said locomotives represent 31 percent of the 
pollution reductions needed to meet Federal air quality 
requirements under the Clean Air Act And that 31 percent really 
caught my eye because the statistics that the EPA gave us is 
that railroads make up less than 2 percent of transportation 
emissions and only about .05 percent of overall greenhouse gas 
emissions. So can you tell me where that 31 percent statistic 
came from? Because I'm having trouble reconciling it.
    Mr. Abbs. Yes, Chair, thank you for that question. So that 
number comes from the--from CARB's State SIP (State 
Implementation Plans) that they turned in for the 2022 SIP 
standard. So it represents the difference in emissions that 
California would need to achieve to meet 2037 Federal Clean Air 
Act requirements for particulate and NOx.
    Chairman Obernolte. All right. Well, I'm going to have to 
chase down why those numbers are so different because that 
seems to counter to the data that the EPA is giving us.
    And, Tyler, let me conclude here. I've got another--a 
minute left here. One of the arguments for completely electric 
zero-emissions locomotives is that even if it's not possible to 
pack enough energy into batteries on a locomotive form factor, 
it is possible to just have tenders that are pulled behind the 
locomotive with more and more batteries. And even if you need 
10 of those tenders to do the job of one diesel locomotive, 
that that's feasible. But, you know, that's the argument. Do 
you see some merit in that? Is that true? Or is that something 
that you are skeptical about?
    Dr. Dick. Well, that's something that my research group has 
been actively looking at. While technically feasible to couple 
up as many tenders as needed to provide the battery power, 
there is the operational consideration of train length. So in 
the United States, roughly 70 percent of the primary principal 
mainline corridors are single track lines, and it can only have 
one train operating at a time. And these trains pass each other 
at very short sections of a double track called passing 
sidings, and the length of those passing sidings can limit the 
length of a freight train. So anytime you take away that 
available length of a freight train and consume it with battery 
tenders or tenders of any sort, you're going to be reducing the 
potential number of rail cars that can be transporting revenue-
earning freight on those trains. And by doing that, you're not 
only earning less revenue per freight train, but you're also 
transporting less freight and making them overall less 
efficient. So there's an efficiency penalty dictated by the 
maximum train length that tenders impose on the network and 
operations.
    Chairman Obernolte. All right, thank you.
    I'll now recognize Ranking Member Foushee for 5 minutes for 
her questions.
    Mrs. Foushee. Thank you, Mr. Chairman.
    We must not forget that this issue at its core is about 
human health and human life. Mr. Abbs, you testified that in 
the community of Richmond/San Pablo rail activities increase 
the risk of cancer by 20 percent. Meanwhile, CARB estimates 
that the rule would decrease cancer risk in communities around 
major railyards by over 90 percent by 2045. Environmental 
justice communities bear the true costs of polluted air, so 
they must be centered in any discussion about costs and 
benefits for policies such as this.
    So my first question is can frontline communities near 
railyards in the Bay Area hope to achieve healthy air quality 
standards without significant reductions in freight rail 
emissions?
    Mr. Abbs. Thank you for your question, Ranking Member. So 
the simple answer is no. We've done significant work in 
frontline communities, especially over the last 10 years, 
communities such as West Oakland, Richmond, San Pablo, that 
are--that have, as I mentioned, locomotive operations, port 
traffic, a lot of industrial facilities. It takes effort in a 
lot of those areas to get reductions to even get those 
frontline communities down to the risks of the rest of the Bay 
Area that doesn't have those industries nearby, but locomotive 
operations and getting those cancer risks down through 
increased locomotive regulations is absolutely critical to get 
even close to what we would like to see in the frontline 
communities.
    Mrs. Foushee. And it's very common for industry to claim 
that ambitious new air quality standards are impossible to 
meet, and new technologies are immature and infeasible, but 
time and time again, new standards are enforced. Our 
environmental--our environment becomes cleaner, and the sky 
does not fall. How does the industry's resistance to rail 
decarbonization mirror other sectors' reluctance to adopt 
previous air quality standards? And should past experience make 
us optimistic about industry's ability to adapt to this rule?
    Mr. Abbs. That's a good question. So our primary role as a 
stationary source regulator means that the Bay Area AQMD 
routinely tightens or strengthens regulations on sources of 
industrial pollution, and we do find--as you say, every time 
we'd like to strengthen regulations to lower emissions, the 
first argument is that it's not achievable, it's not cost-
effective, we're going to leave the Bay Area, we're going to 
leave California.
    But time and time again, what we've seen in California in 
general, we've managed to increase the State's GDP (gross 
domestic product), become the fifth-largest economic powerhouse 
if we were a country, and we've done that by making California 
cleaner. And so I think we can do both, and this regulation 
would definitely get us in that right direction.
    Mrs. Foushee. Thank you for that.
    Mr. Dick, thank you also for your testimony today. As this 
is a Science Committee hearing, we always appreciate the 
presence of technical experts. And we have a firm commitment to 
scientific transparency. Your publication history shows that 
you've authored or co-authored at least 37 papers since 
publishing your dissertation. How many of these papers were 
funded in whole or in part by the Association of American 
Railroads?
    Dr. Dick. Yes, thank you. I'd estimate that, depending on 
the particular topic, most of my papers typically focus on 
railway operations, so approximately half of those publications 
would have had some high-level partial support when I was at 
the University of Illinois from the Association of American 
Railroads through gifts to the academic program there. They're 
given at a very high level.
    Mrs. Foushee. By my count, roughly half of your academic 
research papers, as you noted, have been funded by industry, 
and the primary source of that industry funding has been AAR. 
In fact you even thank AAR for your support in your 
dissertation itself. I want to be clear. Industry-funded 
research is not inherently problematic, and I respect your 
expertise. However, I think it's important for the hearing 
record to reflect that your research funding has been highly 
dependent on support from an organization represented here by 
one of your co-panelists.
    The testimony you presented today is closely aligned with 
AAR's position. That's not a given. There is a wealth of 
scientific research pointing to the technological feasibility 
and cost-effectiveness of railroad companies switching to 
cleaner technologies. So I think it's important to note that 
while 3/4 of the panelists today are coming from--are coming to 
an identical conclusion, that does not reflect the balance of 
the full scope of scientific literature on the issue.
    Mr. Chair, I yield back.
    Chairman Obernolte. The gentlelady yields back.
    I request unanimous consent to include numerous stakeholder 
letters that the Committee has received on this issue into the 
record. Without objection, so ordered.
    We'll go next to my colleague from California. Congressman 
Fong, you're recognized for 5 minutes for your questions.
    Mr. Fong. Thank you, Mr. Chair.
    If I could first go to Mr. Jefferies. As the Chair noted, 
rail is a critical component of our supply chain. As you noted 
in your testimony, California is home to two of the biggest and 
busiest ports in America. The Port of L.A. and the Port of Long 
Beach account for 40 percent of the goods and products entering 
into the United States. And these ports are critical for 
several sectors of the economy, as--whether it's on the import 
side, but of course on the export side as well for especially 
the farmers in my district.
    And my question is if the EPA grants this waiver, could you 
describe in more detail the impact to the supply chain and what 
it would mean to the national freight rail network?
    Mr. Jefferies. Well, the last term you used is key in this, 
the national freight rail network. Railroading is the original 
federally regulated industry, given its inherent interstate 
nature, so things don't happen in a vacuum in one State or the 
other. That's why this regulation is clearly illegal under 
Federal statute.
    But what--one, you're going to--as my colleague said, and 
I'm sure he'd be happy to elaborate on, you're going to put 
some smaller railroads out of business. You're going to 
dramatically increase the cost of transportation by rail, even 
for the larger railroads given the, you know, $1.6 billion a 
year that they are going to be paying to the State because they 
cannot turn their fleet over with a technology that does not 
exist.
    You know, the--I think about this--who has the most 
businesswise reason to profit from this? It's the OEMs, and 
it's the OEMs who are making the case that this capability is 
not out there. And so you're dramatically increasing the cost 
of transportation. What's that going to do? It's going to push 
freight onto the highways, increase congestion, increase wear 
and tear on publicly owned infrastructure, increase emissions, 
and grind to a halt a lot of the free movement of commerce, not 
only in California, but in and out the rest of the country.
    Some of the workarounds we've discussed even at the highest 
level, literally putting traffic onto trucks to move it into 
the State because you don't have the locomotive technology, 
switching locomotive types if the technology did exist at the 
Stateline. That requires a massive amount of buildout of 
infrastructure. That's additional handling, switching, reducing 
transit--increasing transit times, again, making rail 
completely obsolete when it comes to a customer or a shipper's 
desire to move goods around the country.
    Mr. Fong. So just as a follow up, in your assessment as an 
expert in freight railroads, would it be fair to describe the 
supply chain impacts as significantly disruptive?
    Mr. Jefferies. It would be more than fair to describe it 
that way.
    Mr. Fong. And let me move to Mr. Baker if you have anything 
to add to this conversation on supply chain.
    Mr. Baker. I appreciate that. As Ian highlighted, it's a 
seamless integrated national rail network, and I represent the 
short line railroads, which are typically the first and last 
miles. And, as CARB even acknowledges in its own rule tax, this 
rule legitimately threatens the viability of short line 
railroads. I try not to come up to Congress and Capitol Hill 
and speak in hyperbole, but this is an existential threat to 
short line railroads. And if small railroads, which just simply 
can't afford this mandate on anything remotely resembling the 
time that's contemplated, if small railroads go out of 
business, then that freight, it just moves to truck. It either 
moves out of California, it vanishes, or it moves to trucks. 
And so I would say that's devastating for not only the supply 
chain, but also the environment, also public safety, also 
congestion, and also the taxpayer who has to pay for the 
highway maintenance.
    Mr. Fong. Moving to Mr. Abbs, as someone who just came from 
the State legislature, served on the Select Committee on Ports 
and Goods Movement, served during the pandemic and the supply 
chain crisis, my question to you is, how does the State of 
California plan to mitigate the supply chain disruptions that 
are likely to arise because of CARB's regulation?
    Mr. Abbs. Thank you, Congressman Fong. Welcome to D.C. It's 
good to see you again.
    Mr. Fong. It's good to see you. It's like we never left.
    Mr. Abbs. So I'm--you know, obviously I'm with the Bay Area 
Air Quality Management District. I'm not here to talk about 
CARB's overall strategy with respect to supply chain, and so--
and, you know, what they foresee the impacts might be as part 
of this--as part of their locomotive regulations----
    Mr. Fong. If I could specify then, you oversee the Port of 
Oakland. How would you as the--your air quality operations, how 
would you--how would it affect the ports there?
    Mr. Abbs. Well, so as I mentioned before, we do significant 
work in and around the port of West Oakland to try to make that 
port area cleaner for the residents of West Oakland. There's 
about 26,000 residents in and around the port, and they've been 
asking for a cleaner environment for decades. And so the work 
at the port and work at the rail operations related to the port 
is significant to us. You know, we would love it if we could 
get to tier 4 switchers immediately. We would love it if we 
could get to zero-emission equipment as fast as possible. But 
in terms--and so we'd be definitely hopeful that we can do 
that. As I mentioned, incentives coming from the Bay Area are 
not enough, and so we rely on them to meet the requirements of 
the locomotive regulation to do that.
    Mr. Fong. I've run out of time. I think the concern about 
cost is what I was trying to get at in terms of how we mitigate 
these supply chain disruptions. So thank you.
    Chairman Obernolte. The gentleman yields back.
    We'll go next to the Ranking Member of the Full Committee. 
Ranking Member Lofgren, you're recognized for 5 minutes.
    Ms. Lofgren. Well, thank you, Mr. Chairman, and thank you 
to all the witnesses.
    Mr. Abbs, first, I want to thank you for the work that you 
are doing in the Bay Area making the air in my district more 
breathable and, by extension, improving the health of my own 
constituents.
    Now, in your testimony, you note that locomotives account 
for nearly 1/3 of the pollution reduction needed to bring 
highly polluted air basins into attainment of the Clean Air Act 
requirements. Now, the other witnesses today have come citing 
much smaller numbers, contextualizing locomotive emissions as a 
portion of total U.S. emissions or sector-wide emissions. Can 
you please explain this discrepancy? Just pointing to say that 
.6 percent of total U.S. GHG emissions missed the point when it 
comes to protecting the public health of frontline communities.
    Mr. Abbs. Thank you, Congresswoman. I think the context 
that's missing from some of those statements is that it focuses 
specifically on greenhouse gases. This is--the CARB regulation 
is air toxic control measure, and so it's designed to get 
reductions in diesel particulate matter, which is a carcinogen, 
and also to get reductions in NOx, which is an ozone 
precursor.
    So the overall impact of locomotives nationwide may be 2 
percent in terms of GHGs, but really, when you look at it, the 
purpose of the California regulation is to get public health 
benefits and to get public health benefits through reductions 
of diesel particulate, and NOx. There is--as the 
regulation does point out, there are reductions in GHGs that 
are anticipated, but primarily, those health benefits are from 
the air toxics.
    Ms. Lofgren. Thank you. That's very helpful in 
understanding this.
    Now, in your testimony, you cited the CARB figures 
estimating premature death, emergency room visits, cancer 
rates, and those are striking numbers. Can you share what these 
drastically improved health metrics would mean for residents of 
the Bay Area where Mr. Mullin and I represent?
    Mr. Abbs. So when you look at health risks in different air 
basins as part of that locomotive regulation, about 1/2 of 
those costs, those health benefits come from residents in and 
around the South Coast locomotive operations. About a 1/4 of 
the remaining benefits accrue to the Bay Area, and then the San 
Joaquin Valley also gets a significant amount of benefits. But 
between the South Coast, the San Joaquin Valley, and the Bay 
Area, we get most of the--about 100 percent of the benefits, 
and we have about 100 percent almost of disadvantaged 
communities between those three air basins.
    Ms. Lofgren. You know, we recently had a briefing on the 
hydrogen hubs in California and the very aggressive plans for 
the trucking industry in particular to rapidly move that 
industry into zero emissions. I think that's important when it 
comes to not only the Bay Area, but the whole State, which 
leads me--you may not know the answer to this question because 
you're Bay Area-focused in your job, but the children of the 
Central Valley in California have the highest asthma rate in 
the United States, and it's from pollution. And I'm wondering 
if you can identify how much of that would be ameliorated 
through the rail rule? How much would be ameliorated through 
the transition to hydrogen hubs and trucking? Because I-5 is a 
major issue in terms of emission. Do you have that information, 
or do I need to ask someone else?
    Mr. Abbs. I don't have that exact information, but I can 
give you something that may satisfy you at least for this 
hearing, and then I'll work on getting you some more 
information later. CARB did a--what they called a truck-versus-
train analysis where they looked at the pollution disbenefits 
of transporting a similar amount of goods by train and by 
truck. And what they've discovered is that in the 2020 to 2024 
time period, with the advances that we've made in clean 
technology for the heavy-duty trucking fleet, a fleet of trucks 
transporting the same amount as a train has about the same 
amount of pollution, and so the cleanliness of our trucks have 
gotten to the point where they're almost cleaner than the same 
amount of transport by locomotive. And so what we're hoping to 
do as part of this regulation is truly get those locomotives to 
be as clean as they claim they are.
    Ms. Lofgren. Thank you very much. My time has expired, but 
any information you can provide on the questions after this 
hearing would be greatly appreciated.
    I yield back, Mr. Chairman.
    Chairman Obernolte. The gentlewoman yields back.
    We will go next to the gentleman from Texas. Mr. Babin, 
you're recognized for 5 minutes.
    Mr. Babin. Thank you very much, Mr. Chairman. And thank you 
to the witnesses for being here and your testimony. I also 
serve on Transportation and Infrastructure, and this very 
morning we were talking about the emissions--the new emissions 
rule coming down in California.
    Mr. Baker, in your testimony, you mentioned that the 
California Air Resources Board acknowledged that their rule 
would potentially bankrupt the short line industry and stated 
that it is possible that some of these businesses would be 
eliminated if they fail to comply with the rule. CARB sees the 
elimination of a critical player in the supply chain as a cost 
of doing business. Can you speak to the unique nature of short 
line business practices and why meeting CARB's mandate by 2035 
is not feasible because of its potential crippling effects?
    Mr. Baker. Yes, sir. I appreciate the question. The unique 
nature of short lines, which I know you're very familiar with 
from your time on the T&I Committee, the origin story of short 
lines really is we're keeping lines viable that are really on 
the margins, right? We got them from class 1 railroads in the 
first place because they didn't make any money, and we've done 
everything we can to run as lean, as efficiently as possible, 
try to get one more customer, try to do everything we can for 
existing customers, and it's widely considered a pretty good 
American success story that most agencies we've encountered 
would like to double down on and improve.
    But CARB's rule contemplates at such a dramatic exponential 
increase in how much we would have to pay for locomotives and 
mode of power that it would put us out of business. And that's 
so obvious that they had to acknowledge it themselves in the 
rule. And then, you know, from our point of view, the 
consequences of that are relatively obvious, but if we're out 
of business, that truck--that freight can't move by rail 
anymore, and that destroys the seamless integrated rail 
network. That's bad for the economy. That's bad for the 
environment. It's bad for public safety.
    Mr. Babin. Thank you very much.
    Mr. Jefferies and Mr. Baker, you all touched on this in 
your testimony, but if this misguided policy goes into effect, 
what will the impact of this rule be on constituents outside of 
the State of California and on supply chains across the 
country?
    Mr. Jefferies. Maybe I'll take a first crack, and Chuck can 
cleanup my mess. So, you know, there's no such thing as a one-
State regulation when it comes to the interstate rail network. 
That's why there's such strong Federal preemption in law 
because, as I mentioned in my opening statement, nearly 70 
percent of our locomotive fleet moves in and out of the State 
of California in any given year. And so what does that do? One, 
at the very base case scenario, this rule dramatically 
increases the cost of providing rail transportation and most 
likely shifts a lot of freight onto the highways. And so what 
does that do? It makes our customers pay more. It makes 
consumers pay more. It adds stress to the public infrastructure 
by pushing more trucks, more traffic onto the highways, 
increasing congestion, impacting the daily consumer.
    Mr. Obernolte and I just talked about the desire to get 
trucks off the highway and onto the rail. If you want to reduce 
emissions right now, let's get trucks off the highway onto the 
rail, three to four times more efficient when it comes to that. 
And so, you know, you can't understate the impacts across the 
board.
    Mr. Babin. Right. Thank you.
    Mr. Baker?
    Mr. Baker. He said that very well. I would note that 
there's a long history, for better or for worse, of other 
States copying CARB's rule, so if this rule goes into effect, 
if EPA approves it, I think we could expect some number of 
other States, you know, maybe around 10 or 15 as a reasonable 
estimate, who would copy this rule and make it even more 
national. But I would say California is so big, and nobody 
would dispute that. California is so big. A California rule is 
essentially a de facto national rule as it affects the 
interstate rail network. So all the problems we've talked about 
that would come in California would be--you'd see nationwide 
very quickly.
    Mr. Babin. Thank you very much. Less than a half a minute. 
Mr. Baker, it seems like the California Air Resources Board is 
choosing winners and losers here. If they are able to move 
ahead with this rule, short line railroads look to be slated 
for the losers list. Can you talk about just for a second why 
short lines in particular are not going to be able to comply 
with CARB's compliance deadline and what it means for short 
lines around the country?
    Mr. Baker. I appreciate that question. Going back again to 
the origin story of short lines and how we have to really make 
a small business try to run as efficiently as possible, a 
typical short line is buying a used locomotive, maybe about 
$100,000. They tend to make them last 40, 50, 60 years. The 
idea of a rule that would say no locomotive older than 23 years 
old can run in California is--if it weren't so serious, I would 
almost say it's laughable. But, I mean, I say that to short 
line railroads, and they look at me with disbelief like, well, 
all of our railroads or all of our locomotives are older than--
--
    Mr. Babin. Amen.
    Mr. Baker [continuing]. 23 years old.
    Mr. Babin. OK. Thank you. And my time's up. Thank you.
    Chairman Obernolte. The gentleman yields back.
    We'll go next to my colleague from California. Congressman 
Mullin, you're recognized for 5 minutes. And nice job on the 
baseball field last night.
    Mr. Mullin. I'm not going to be commenting on that at this 
time. Thank you, Mr. Chair.
    Thank you all for coming today. I appreciate your 
testimony, in particular, Mr. Abbs, for coming to share how 
your office improves the lives of Bay Area residents, including 
those in my district in the San Mateo and San Francisco 
counties.
    And, first, I want to start by saying I've long been a 
proponent of reducing emissions on railroads. I was one of the 
many leaders involved in the nearly finished effort to 
electrify the Caltrain corridor, which runs through my 
district. This has taken dozens of diesel-powered locomotives 
off the rails, reducing emissions for residents, and providing 
faster and more frequent service. And while Caltrain is a 
localized issue on a commuter rail service, railroads across 
the State continue to contribute to greenhouse gas emissions 
that should be phased out as quickly as practicable.
    I am sympathetic to the industry's concerns over cost and 
timeline, yet CARB's rule provides flexibility to ensure the 
industry remains viable and the transition is realistic. And 
without such regulations, communities like mine and many others 
are the ones who pay the costs in dirty air and in the impacts 
of climate change such as sea level rise. And, as my colleagues 
said earlier, these costs are dramatically higher than the 
upfront investment that industry will make to adopt clean rail 
technology.
    So my question, Mr. Abbs, in your firsthand experience, 
what are the costs that Bay Area communities are paying when it 
comes to living with air pollution and the consequences of 
climate change, including sea level rise? In other words, 
what's the cost of doing nothing compared to the cost of 
transitioning to cleaner locomotives?
    Mr. Abbs. Thank you for that question, Congressman Mullin. 
So just before I answer that, I'll just also note that the 
Caltrain electrification project, hopefully starting up in 
September of this year, replacing 75 percent of the trains, 
will yield the GHG benefit, but that's because they're going to 
zero-emission trains, so 176,000 tons per year of GHGs, 2 
million tons by 2040.
    Your question on the risks of--or the costs of doing 
nothing, the last 10 years in California, we have rarely gone a 
month during the summertime when we haven't had extreme 
wildfire smoke from wildfires, orange skies. California 
delegation members realize that, in recent years, other parts 
of the United States have woken up to problems that we've been 
dealing with in California for decades now. Sea level rise, 
obviously, it's a big deal in the Bay Area because we're pretty 
close to the sea, and, you know, we have airport.
    We have San Francisco, which is looking at potentially 
billions of dollars to stabilize themselves from sea level 
rise. We have Highway 37 that we need to figure out a way to 
keep that high enough to withstand high tides. And so the cost 
of doing nothing in the Bay Area is substantial, and so that's 
why going to zero emission as part of that locomotive 
regulation is going to have some serious long-term benefits for 
the Bay Area.
    Mr. Mullin. Thank you for that. And, as you mentioned in 
your testimony, the air district was the first regional air 
pollution control agency in the Nation. It predates the Clean 
Air Act. And given that, there's a decades-long history of 
navigating the puzzle of local, State, and Federal air 
pollution regulations is for the benefit of anyone breathing 
California air. So can you please describe the air district's 
role and its limitations when it comes to addressing air 
pollution in the Bay Area? And how does its authority differ 
from CARB's?
    Mr. Abbs. Thank you for that question. So the Bay Area Air 
District, is primarily, we deal with the stationary source 
regulation, but at the same time, every air district in 
California has to meet certain Clean Air Act standards, the 
attainment standards for ozone, different forms of particulate 
and other criteria pollutants. And so while air districts can 
regulate stationary sources, a lot of the pollution that we see 
that affects those Clean Air Act standards come from sources 
which the air district really has no authority over.
    And so what you've--what you may have seen over the last 
several years is air districts like the San Joaquin Valley Air 
District, the South Coast Air District, the Bay Area Air 
District have been very strong advocates for actions at the 
State level and at the Federal level to reduce mobile source 
pollution because, without those reductions, most of California 
cannot meet Clean Air Act attainment standards. There's 36 
counties in California right now that are in non-attainment of 
the Federal ozone standards.
    Mr. Mullin. Thank you for that, and I'll just conclude by 
mentioning that it's my understanding that the EPA made it 
clear in November 2023 that CARB indeed has the authority to 
regulate locomotives. And with that, I'll yield back, Mr. 
Chair.
    Chairman Obernolte. The gentleman yields back.
    We'll go next to the gentleman from Georgia. Mr. McCormick, 
you're recognized for 5 minutes.
    Mr. McCormick. Thank you, Mr. Chair.
    Mr. Abbs, you just brought up an interesting point about 
the ocean rising. How much has it risen in the last 50 years?
    Mr. Abbs. I'll have to get back with you on that, 
Congressman.
    Mr. McCormick. Not a significant amount, obviously, 50 
years. Since 1970 what's the carbon emissions--the carbon 
content of the atmosphere? Is that greater or less than what it 
was in 1970?
    Mr. Abbs. Could you repeat that question again?
    Mr. McCormick. Carbon content, carbon dioxide levels in the 
United--in the entire Earth atmosphere? Was it greater or less 
than it was in 1970?
    Mr. Abbs. I would say greater.
    Mr. McCormick. You care to state that--bet money on that?
    Mr. Abbs. I'll let you answer the question either that I'm 
right or wrong.
    Mr. McCormick. OK. And what percent is atmosphere--is made 
up of carbon dioxide, percentage of the atmosphere?
    Mr. Abbs. It's a little over 400 parts per billion.
    Mr. McCormick. So .04 percent, right? Of that, how much 
comes from human beings? About 11 percent. About how much comes 
from the United States? 14 percent. Of that, how much comes 
from trains in the United States? Point 5 percent. So we're 
talking about eliminating .00003 percent of the Earth's 
atmosphere, carbon dioxide. That's what we're talking about. Is 
that a negligible effect when it's compared to nitrogen at 71 
percent? Yes, thank you.
    So I love science. I love science. Let's talk about 
science, no, not as a religion, but as science because that's 
what this is about. And how much heat is produced when we have 
to produce massive amounts of electricity? That's what this is 
about. Do we want to hamstring ourselves by spending trillions 
of dollars based on some California code of a religion of 
carbon dioxide?
    Georgia's ports, along with the intertwined railroads and 
highways--and I'd say Georgia is famous for its railways for a 
long time now--are the epicenter of both Georgia and the 
Southwest U.S. economy. Ironically, Georgia typically benefits 
from California's outrageous regulations because we get a lot 
of business that moves to our State because of it. However, 
California's Air Resource Board's--CARB--latest rule to make 
freight rail zero emissions jeopardizes the interconnected 
freight rail network. Meanwhile, the EPA's own study stated 
that freight railroads contribute to-what did I say--.5 
percent, .5 percent of the total U.S. greenhouse gas emissions. 
I already talked about the negligible effect we began with. If 
you--matter of fact, if you eliminate all the cars' emissions 
in the United States, .000167 percent in case you're wondering 
is how much of the atmosphere we're talking about. Negligible, 
guys, that's science.
    If California received this waiver from the EPA for the 
proposed rule, it would allow California to dictate the 
emissions policy for the entire country at devastating economic 
impact. What can we spend that money on? If you want to have a 
scientific discussion about how we save the Earth, don't start 
with that because, by the way, based on a Senate scientific 
study, Pluto, Mars, Jupiter are all heating, too. Is it because 
of their carbon emissions? Of course not. Let's have a real 
scientific discussion about climate change. This is what's 
driving me crazy, guys, when we have these conversation.
    Mr. Jefferies, can you further explain how California's 
decision would impact railroads, supply chain, and military 
bases in Georgia?
    Mr. Jefferies. Well, because we operate a nationwide 
interconnected network, whatever happens in California, 
whatever regulations in California are effectively national 
regulations because 70 percent of our locomotives move in and 
out of the State of California.
    And I should just point out that maybe most folks on this 
Committee may not be aware, but we are self-funded. We fund all 
of our own infrastructure, all of our own investments to the 
tune of about $21 billion a year. This is not coming from the 
Federal Government. These are businesses decisions that we are 
making, and so it----
    Mr. McCormick. Unfunded mandates, right?
    Mr. Jefferies. Absolutely.
    Mr. McCormick. Love it when the government does that.
    Mr. Baker, in your testimony, you mentioned that the 
California Air Resource Board acknowledged that their rule 
would potentially bankrupt the short line industry and stated 
that it is possible some of these businesses would be 
eliminated if they fail to comply. California sees the 
elimination of a critical player in the supply chain as a cost 
of doing business. It's crazy.
    The Georgia Northeast Railroad is a class 3 short line that 
runs through my district. Can you speak to the unique nature of 
the short line business practices and why meeting California's 
mandate by 2035 is not feasible?
    Mr. Baker. Yes, sir. The Georgia Northeastern Railroad is a 
great example of a typical short line, but they're maintaining 
lines in small towns and rural America that are marginal, 
frankly, that otherwise are at risk of not existing. And to do 
that, they have to run efficiently, smart, and clean, and so 
they do everything they can to get cleaner, including upgraded 
cleaner locomotives when they can, but they just can't afford 
this mandate. It would force many of them out of business in 
California and if it went national in Georgia, too.
    Mr. McCormick. So with that, I'm going to rest my case that 
this is not based on science. This is based on California's 
religion that doesn't have any effect on the outcome of the 
atmosphere, that there is global climate change, but it's not 
due to trains. We don't need to spend--we don't need put 
businesses out of order and change everything based on 
California's idea that they're going to fix the world with 
electronic trains. I'm sorry. With that, I yield.
    Chairman Obernolte. The gentleman yields back.
    We'll go next to the gentlewoman from New York. 
Congresswoman Tenney, you're recognized for 5 minutes.
    Ms. Tenney. Thank you, Mr. Chairman, and thank you, Ranking 
Member, and thank you to our witnesses today.
    I just want to first go to Dr. Dick and ask you, you were 
earlier asked about funding for your research. It was alluded 
to or suggested that your research is tainted. My understanding 
that your research has also been funded by the Federal 
Government. Is that correct?
    Dr. Dick. Yes, that is correct. Just to go back and looking 
back over my funding history, roughly maybe 5 percent of my 
total funding was received from the Association of American 
Railroads. The majority of my funding related to alternative 
energy locomotives was received from CARB itself, the Federal 
Railroad Administration (FRA), and also the Department of 
Energy's Advanced Research Projects Agency--Energy, ARPA-E, on 
several--I do projects on that front. The vast majority of my 
funding on the alternative energy locomotive stuff has come 
from DOE and FRA and not from the Association of American 
Railroads.
    Ms. Tenney. Those sound pretty independent to me. Thank you 
for that. Thank you for clarifying that because it does--your 
record does show that you actually do indeed get funding, as 
you just stated, from the California Air Resources Board 
itself, so--this is the rule that we're contesting here.
    And I just want to say--just ask you again--are you--can I 
just get a little bit about your background? So my question to 
you, Dr. Dick, is it says you've been studying civil 
engineering and railways since 1999. Is that correct?
    Dr. Dick. That's correct.
    Ms. Tenney. OK. How about Mr. Jefferies? You've been 
involved in rail issues since 2009 and served in the Inspector 
General's office at the Department of Transportation. Is that 
correct?
    Mr. Jefferies. That's correct.
    Ms. Tenney. Mr. Baker, you have been involved in rail 
issues since 2004. Is that correct?
    Mr. Baker. That's right, 20 years.
    Ms. Tenney. OK. Mr. Abbs, I couldn't find anything in our 
research on--in your bio on railroads or rail systems. Have you 
ever worked on a railroad or for the rail industry?
    Mr. Abbs. No, I have not.
    Ms. Tenney. OK. Did you study railroads or any of these 
issues with peer-reviewed studies like the--Dr. Dick and some 
of the other men sitting here?
    Mr. Abbs. No, I haven't.
    Ms. Tenney. OK. So this hearing is about the proposed 
California Air Resources Board--I'll call it CARB. I don't like 
to talk about carbs, I don't know--and what this regulation 
will have on the national rail network, not on environment and 
pollution control. It seems to me that you're more of an 
environmentalist and not so much an expert on railways and 
makes you kind of like an odd witness for this because your 
expertise is not on how to conduct railroads more successfully. 
Is there anything that--in this regulation that you have done 
or anything that deals with railways, not environment, in terms 
of what this regulation would be about?
    Mr. Abbs. Again, I have no experience with railways.
    Ms. Tenney. So I know you were--this question has probably 
come up, and I--we've been in and out of here, but I want to 
just say, do you know what percentage of U.S. freight is 
transported on railways?
    Mr. Abbs. No, I do not.
    Ms. Tenney. OK. It's 40 percent. I think somebody talked 
about that earlier. So this is an easy one for you, Mr. Abbs, 
because I know Mr. McCormick--or Dr. McCormick just explained 
this to you. But what percent of the U.S. greenhouse gases are 
caused by railroads?
    Mr. Abbs. I believe the number was 2 percent.
    Ms. Tenney. Point 5 percent, I think, was the correct 
answer. Would you agree with that?
    Mr. Abbs. I'll take your word for it.
    Ms. Tenney. Thank you. OK. What percent of U.S. 
transportation greenhouse gases are caused by railroads? I 
think we--Mr.--Dr. McCormick went over this. He's a Marine, 
too, so he's a Marine and Dr. McCormick. He's got a lot of 
titles--and scientist. The answer is 1.7 percent. I think--I 
believe that was asked. So if 40 percent of freight is 
transported by railways, and yet they only account for 1.7 
percent of transportation-related greenhouse gases. Why would 
CARB target railways instead of, say, the trucking industry?
    Mr. Abbs. Yes, thank you for that question. So CARB has 
done extensive regulations with the trucking--on the trucking 
industry with respect to California and, as I mentioned earlier 
in questions, has done a truck-versus-train analysis on a 
load--equivalent load on a train versus a truck and found that 
in the 2020 to 2024 time period, the particulate matter and 
NOx emissions from a----
    Ms. Tenney. Let me take--reclaim my time and just--because 
I'm running out of time, but I know that there's this vision 
and a need to magically transform us into complete electric. I 
come from the State of New York, very similar to a regulatory 
regime that we have in California, and I worry about what could 
happen in a State like New York with--you know, we can get 
five, six feet of snow in just a 24-hour period from the lake 
effect snow from either Lake Erie or Lake Ontario. It would be 
catastrophic, it would be dangerous, and people would die, 
including schoolchildren are now being forced to be on electric 
buses in the State of New York with policies that are just only 
focused on electricity and only on electrification and not on 
safety, science, and those things. And that's what worries me 
is that we're trying to--we have to look at the realities of 
what we're dealing with with people and children and our 
communities that we serve.
    And that's why I feel like someone with an expertise in 
railways, transportation, and all these things, maybe with your 
background mixed in with that would be more suitable, but you 
don't seem to have that background as far as dealing with the 
practical aspects of railways.
    So with that, my time is expired. Really, thank you so 
much, Mr. Chairman, and thank you to the witnesses.
    Chairman Obernolte. The gentlewoman yields back.
    That concludes our question-and-answer period. I want to 
thank all of the witnesses for your valuable testimony and all 
of the Members for the questions. The record will remain open 
for 10 days for additional comments and written questions from 
Members.
    This hearing is now adjourned.
    [Whereupon, at 3:24 p.m., the Subcommittee was adjourned.]
